Review on Kawasaki Ninja 400 Z400 Slip-On Exhaust System Including Muffler For Improved Performance - Compatible With Models From 2018, 2019, And 2020 by Evan Burnside

Very easy install! Just look at the pics from the other peoples posts. One thing I did was buy the exhaust expander. I only need to turn a few times! Don’t want to over do it ! For the other piece of pipe. I just sprayed a little chain lube on and used a block of wood and tapped it with a hammer to go down. After it was on it was easy to turn. You must line up the pipe inline where the springs connect for proper fit. Mine was turned so I had to re adjust . Once aligned perfect! Also there are two set of springs. I used the small but bigger hooked ones. You will see the difference. Pick the ones that work for you. I took the baffle out as well. I want people to be able to hear me. And now they can!
